WHAT IS THE PROGRAMFOR SEQUENTINSTALLERS

I f “SEQUENT” is the most

updated timed sequential gaseous

injection system and continuously

developed by BRC, the PC inter-

face is the most evolved instru-

ment for the gas installation setting

up and diagnosis BRC has ever

produced and distributed.

We could think about the “FLY

SF” electronic control unit as the

brain of “SEQUENT” system which

has always the full control in defin-

ing the carburation, in doing the

different calculations on sensors

signals and in updating continu-

ously its map, etc. In order to carry

out these operations, the ECU

needs to be programmed, calibrat-

ed, to know what are the maps

and the parameters to be used for

the vehicle where i t has been

installed.

The instrument to fully control

the ECU and of course SEQUENT

system is the PC installers pro-

gramme. Practically in order to

rich, poor, change the change-over

parameters, increase or decrease

the spark advance ignition, set the

gas level sensor inside the tank,

verify if there are mistakes in the

electrical installation, display the

physical (gas pressure and tem-

perature, suction manifold pres-

sure, etc.) and functional parame-

ters (injection times and injectors

duty cycle, oxygen sensor, map

centering, etc.) you do not need to

turn screws, hand-grips, “real”

switches but all operations will be

carried out in a “virtual” way by

using the PC programme as inter-

face.

TO WHOM IS THIS GUIDEADDRESSED

This guide is useful to those

who:

instal l or adjust gas

“SEQUENT” installations

• have already downloaded the

“SEQUENT” users programme in

the PC

• need a reference guide for the

PC programme

• need to understand and deep-

en the operat ion pr inciples of

“SEQUENT” system

• need a support for the setting

and solving of “SEQUENT” system

problems.

INTRODUCTION

For further information on

“SEQUENT” system please refer to

the other guides and informative

sheets printed by BRC.

• SEQUENT user ’s guide.

This is the easiest way to have

basic and general information

about the SEQUENT system

installation.

Inside you can find:

• notions regarding the system

operation principle and its struc-

ture,

• a detailed description of all the

components,

• indications for both mechanical

and electrical installation.

• Types of installation.

It contains generic fitting and

electrical plans for different

types of installation you could

face. The listed cases are main-

ly grouped according to the

cylinders number, their position

and the vehicle power. It is use-

ful especially when installers do

not have specific instructions.

• Specific instructions.

All mechanical instructions and

electrical plans of a particular

vehicle which has been studied

at BRC plant where both electri-

cal connections and mechanical

position of the components are

precisely indicated. In these

cases BRC will supply a dedi-

cated kit containing all the

brackets and possibly the dedi-

cated changeover switch too.

This kit has to be paired to a

basic one and to a standard one

as indicated in the instructions.

USEFULREFERENCES

Modular Common Rail system for gas

Briefly all you need to “talk” with

the SEQUENT ECU is:

1. Portable PC

2. SEQUENT interface cable

(code DE512114)

3. PC SEQUENT Software on

CDROM

4. SEQUENT hardware key

Except for the PC which could

be ordered to BRC, all the other

components are contained inside

the kit “Software for SEQUENT”

code 90AV99002033.

In the picture 1.1 you will see

the SEQUENT interface cable while

in pictures 1.2A and 1.2B there is

the hardware key suitable for paral-

lel door in the first one and for USB

door in the second. The hardware

key for SEQUENT is easily recog-

nisable for the word SEQUENT or

SF hot pressed on one side; others

hardware keys even if suitable for

other BRC systems will not work.

In the next paragraphs a short

description with all characteristics

of what above.

Pic. 1.2.A -Hardware key forparallel door

Pic. 1.2.B -Hardware Key forUSB door

For this purpose and on

demand BRC could supply portable

PC containing the updated software

whose functionality has been

already tested.

1.2 THE INTERFACECABLE FOR SEQUENTINSTALLA TIONS

This cable contains an electron-

ic circuit able to translate the ECU

signals corresponding to the motor-

car standard ISO 9141 and ISO

15031 into ones suitable for the PC

that is according the standard of

RS232 serial communication. The

cable is not compatible with the

other ones used for BRC sys -

tems, such as FLYING INJEC-

TION, JUST and JUST HEAVY.

It could be ordered to BRC with

the code DE512114.

1.3 SOFTWARE ANDHARDWARE KEY

The software is contained in the

CDROM supplied in the kit code

90AV99002033 “Software for

SEQUENT”

The CDROM also contains all

updating for the ECU programming

and these are anyway available in

the most updating version on inter-

net BRC site at the following

address: http:// www .brc.it.

8

The installation could be carried

out either through CDROM or

diskettes downloaded from internet

at http://www.brc.it.

In the same way it is possible to

update the PC software and all

ECU programming files (software,

loader, maps and adjustments)

either through CDROM or diskettes

downloaded from Internet.

Besides SEQUENT program

which allows to control and pro-

gram the ECU, in order to program

an ECU it is necessary to transfer

on the ECU itself the following files:

• The program making the ECU

operate.

• The loader, to go from an

already existing program to a

new one.

• The files containing the maps

of the developed vehicles (the

ones with name type AAP).

• The files containing the setting

of the developed vehicles (the

ones with name type FSF).

Let’s start from the beginning

and try to carry out the installation.

Let’s examine both programming

cases: with CDROM and with

diskettes.

2.1 “SEQUENT” SOFT -WARE INSTALLA TION ONPC WITH CDROM

3.1 OPENING PAGEDESCRIPTION

After having correctly carried out

the installation and if the Hardware

Key has been introduced in the

printer door or USB one, it is possi-

ble to start and use SEQUENT pro-

gram. To start cl ick twice

SEQUENT icon on the PC screen

or point the low left angle of the

screen with the mouse choosing

”Start” > Programs > SEQUENT.

BE CAREFUL!: for a correct

visualisation of the program

pages, hide the Windows® “instru-

ments bar” (see picture 3.1). To do

that place the mouse pointer on the

bar where there are not icons of

opening programs, click on the right

key, choose “Properties” and finally

select the options “Always fore-

ground” and “Automatically hide” as

indicated in picture 3.1.

During the first start (pict. 3.2)

SEQUENT program is written in

English. To change language click

on UTILITY.

In the new menu click on

“CHANGE LANGUAGE”; select the

language you prefer and click on

CHOOSE (pict. 3.3).

A window with the writ ing

“WARNING” will advice the user he

is changing the language. Click on

OK and go out the program with

EXIT.

11

3. STARTING OFTHE PROGRAM ANDITS STRUCTURE

Pic. 3.1 - Hide Windows® instruments bar

Fig. 3.3 - First start – language selection

Fig. 3.2 - First start – language change

Starting the program again it will

be displayed in the new selected

language.

In describing this guide we obvi-

ously choose English one.

When starting again the window

of the program will be as shown in

picture 3.4.

The big icon with SEQUENT

symbol is easily recognisable;

when the mouse pointer is on the

icon its shape will change into a

question mark while clicking on the

left key you open a window with

some information on the installed

software as indicated in picture 3.5.

The software version contained

in the PC can be read down on the

right.

At the bottom the screen has 4

keys called “main keys” on which

we have 4 files; PROGRAMMING,

SETTING UP, DIAGNOSTIC and

UTILITY.

Their use will be explained later.

Over these files there is another

key with the word “EXIT”. By click-

ing on this one you quit the pro-

gram; if you do not modify or if you

save all changes, the program will

immediately close. Otherwise, if

changes and operations have not

been already saved or memorised

on the ECU, the program will ask

the user if he wants to save them or

not.

BE CAREFUL!: by answering

not, all changes will be lost

and it will be not possible to get

them back.

At the bottom of the screen

there are two narrow and long files

covering all the screen width. The

left one displays the current com-

munication condition (Fastening,

Communication, OK, etc.) while the

right one displays possible commu-

nication errors as, for example,

when the ECU programming is

stopped or other events occur.

3.2 MAIN KEYS

As already stated, the main

keys are 4 and are located at the

bottom of the screen.

All the files are closed (see pic-

ture 3.1). Each key has a writing

under the file drawing and from left

to right we have:

• PROGRAMMING

• SETTING UP

• DIAGNOSTIC

• UTILITY

Please note the underlined let-

ter.

The basic concept to keep in

mind to use this program is that

each main key corresponds to a

12

Pic. 3.4: SEQUENT opening page

Pic. 3.5: SEQUENT opening page after clicking on the icon

main function. To better understand

this philosophy you can imagine

each main key is a big drawer con-

taining all the necessary equipment

to develop an operation. When you

decide to perform it, open the draw-

er (or better cl ick on the key),

choose the equipment and carry

out the desired operation

For the ECU programming refer

to “PROGRAMMING” key, for the

setting up of an already pro-

grammed ECU choose “SETTING

UP”, to verify possible installation

errors or to test the actuators

choose “DIAGNOSTIC” and finally

to select some program options

(i.e. language, communication

parameters, etc) open the “UTILI-

TY” drawer.

By clicking on each key, the file

will open and you will see the con-

tents of the icon coming out. At the

same time on the left side of the

screen some keys appear, each

one with a specific task: these are

the before keys mentioned.

Each main key can be selected

by clicking the mouse or keeping

the ALT key and contemporarily the

underlined letter corresponding to

the key pushed (i.e. ALT+P for

PROGRAMMING, ALT+G for SET-

TING UP, etc.).

It is possible to select the key by

using the keyboard arrows up and

down: the red key is the selected

one.

By pushing the enter key on the

keyboard, you obtain the same

effect of clicking on the red key

with the mouse.

In the next paragraph there is a

short description of main keys.

Please refer to next chapter for the

detailed description including com-

plete procedures to use for each

single function.

3.2.1 “PROGRAMMING” KEY

This key allows to program the

ECU whether if i t is virgin or

already programmed. It is possible

to carry out both of them through

recorded files or files supplied by

BRC (choosing the key “FROM

RECORDS” ) and the self-map

(choosing the key “AIDED PER -

SONALISED” ). These two keys

appear on the left of the screen

when selecting the main key “PRO-

GRAMMING”.

3.2.2 “SETTING UP” KEY

It contains all the necessary

functions to modify maps, adjust-

ments, changeover parameters and

everything could effect SEQUENT

installation operations. By using the

SETTING UP instruments it is pos-

sible to revise every phase of the

aided procedure separately from

the others, to change the parame-

ters of petrol to gas change-over,

correct the self adapting maps, etc.

3.2.3 “DIAGNOSTIC” KEY

It allows to see the values in

order to understand if there are

possible problems or installation

mistakes, to verify the type of soft-

ware, loader and maps unloaded in

the ECU, to test the correct opera-

tion of actuators, injectors, sole-

noidvalves, relays, etc.

3.2.4 “UTILITY” KEY

It groups all the general utility

instruments not included in the pre-

vious categories. These allow to

effect some useful operations to

update the program or to modify

some aspects: you can change lan-

guage, communication parameters

with the ECU, display electrical

plans, extract the map and the set-

tings from the ECU and save them

on the PC, manage the files con-

taining already known vehicles

maps, create diskettes to transfer

the maps to another PC, update all

data on the PC.

13

4.1 PROGRAMMING FILESTYPE

The FLY SF ECU programming

procedure is based on the down-

load of three different types of

files:

1. S19 File

2. FSF File

3. AAP File

4.1.1 S19 FILE

The files with S19 extension

contain the algorithms and the

strategies used by SEQUENT sys-

tem. Each time you effect a new

programming of the ECU it is

advisable to update the S19 soft-

ware with the last version available

in the PC. Obviously the PC has to

be updated too. This allows to

have all the developed functions

and strategies available.

To better clarify the function of

S19 files, we could say that it cal-

culates the exact gas flow to sup-

ply the engine with and pilot the

injectors by analysing the vehicle

specific parameters (FSF file), the

map (AAP file) and all data coming

from the different sensors.

4.1.2 FILE FSF

The FSF file contains the spe-

cific data of the converted vehicle.

For example the type of installa-

tion (LPG or CNG), the engine

type (vacuum or LPG turbo), all

calibration parameters of the sig-

nals coming from the acquired

sensors, the change-over parame-

ters, the possible parameters for

tip-in strategies and the advance

setting up ones.

4.1.3 AAP FILE

The AAP file contains the vehi-

cle map. In particular the petrol

reference map, the gas one and

the map concerning cells condi-

tion. Cells condition map is useful

to identify the type of vehicle oper-

ation in the different operating

area, identified by MAP engine

revolution couples. These cells

could be Open-Loop or Closed-

Loop type.

4.2 ECU PROGRAMMING

In case you need to program an

ECU, it is necessary to select the

4. PROGRAMMING

Pic. 4.1: Guided personalised procedure steps

screen. There are two types of

programming available:

• Aided Personalised

• From records

4.2.1 AIDED PERSONALISED

PROGRAMMING

This type of programming has

to be carried out when you wish to

convert a new vehicle whose map

is not available. In this case start

the configuration of the person-

alised parameters and then the

real self-maping. The aided proce-

dure consists of 8 steps for LPG

and 9 for CNG as indicated in pic-

ture 4.1.

To enter this procedure, select

the Programming key at the bot-

tom of the screen and then the

Aided Personalised one, on the

left. The technician will be guided

step by step through all the differ-

ent phases of the procedure by a

red capital writing in the centre of

the screen. It is possible to go

through this procedure taking one

or more steps backwards or FOR-

WARD, by using the PREVIOUS

or NEXT keys at the bottom of the

screen (see picture 4.4b) or by

using PgUp and PgDwn keys on

the keyboard.

To correctly effect this proce-

dure, respect the conditions indi-

cated at the top of the screen (see

picture 4.2) displaying each step

the correct condition of:

• Engine (on or off).

• Ignition key (connected or

not).

• The changeover switch (gas

or petrol position).

• The vehicle (stopped or run-

ning).

Be careful: with the aided cali-

bration procedure all the parame-

ters on the ECU will be lost.

Hereunder the explanation of

the Personalised Aided Procedure

steps.

4.2.1.1 Type of installation

As shown in picture 4.3 this is

the first step and allows to select

the type of equipment installed in

the vehicle: LPG or CNG.

In case of a usual LPG or CNG

installation, after selecting the cell,

digit ENTER. Automatically the

ECU will receive the software and

a standard map to calibrate the

vehicle.

After sending the data the pro-

gram will ask to disconnect and

connect the ignition key again. At

the end the ECU contents will be

read and the program wil l go

directly to the next step without

further intervention of the techni-

cian.

15

Pic. 4.2 - Conditions at the top of the screen

Pic. 4.3 - Aided Procedure – type of installation

NOTE:

When entering this screen,

before doing any operation, the

PC program veri f ies the ECU

loader version and compares it

with the last downloaded one. If

the ECU loader is not updated, a

message will ask to do that (see

picture 4.3); in this case it is not

possible to continue the aided pro-

cedure until the ECU contains the

updated version (see paragraph

4.2.2 for procedure).

In particular cases indicated by

BRC, it could be necessary to

download a different software

by using “ADVANCED” key.

Clicking on it the following pos-

sibilities will appear:

• Default: it corresponds to the

software normally supplied by

BRC. Without a special authori-

sation given by BRC techni-

cians it will be possible to use

only standard software.

• Custom: it corresponds to

particular software used for

test ing and development.

These ones have to be used

only if indicate by BRC techni-

cians. After choosing this

option, select the software and

click OK in the window for the

software selection (see picture

4.4).

4.2.1.2 Installation and injectors

Calibration

This is the second step both for

LPG and CNG. It needs to specify

further information about the

installed equipment. Particularly it

allows to indicate if it is a vacuum

or a LPG turbo installation. As indi-

cated in picture 4.4b, in the section

where you can choose between

the above options there is the indi-

cation of the choice between LPG

or CNG confirmed in the previous

step (for technician convenience)

but no possibility to change it (the

writing is grey) To change you

have to cl ick on Previous and

repeat the procedure explained at

step 1. In this screen you can

select the installation characteris-

tics too:

• Injector type: indicates the

installed type of gas injector

choosing among the available

ones;

• N. of Genius: indicates how

many genius reducers have

been installed. Mostly it is one

so that this is the set value; it is

necessary to modify it only if

you have two;

• N. of P1 Sensors: indicates

how many P1 pressure sensors

have been installed. The set

value is one. Modify it if you

16

Pic. 4.3a - Aided Procedure – type of installation – not updated loader

Pic. 4.4 - Aided Procedure – type of installation clicking on “OTHER”

need to install two (refer to

installation plans to know how

many sensors are needed).

• N. of Injectors : indicates the

total number of installed gas

injectors. Mainly they are 4 and

this is the set value. A message

will indicate the technician the

number of FLY SF ECU he has

to instal l according to the

selected injectors number.

Finish and verify the introduced

values, then click on NEXT to con-

tinue.

A similar section could be

act ivated from the main

screen, outside the aided proce-

dure, by selecting Setting up -->

Type of Installation

NOTE: By clicking ADVANCED

key in the installation section, it is

possible to set operation limits

concerning the rpm signal and the

MAP manifold pressure (picture

4.4c). Normally this operation has

not to be carried out unless indi-

cated by BRC technicians. In

detail you could set:

• Rpm Min: it is the minimum

rpm value in the maps: usually

it is suitable to set a value of

about 300 rpm under the idling

condition value;

• Rpm Max: it is the maximum

rpm value in the maps: usually

it is suitable to set a value of

about 500-600giri/min under

the vehicle rev up value;

• MAP Min: it is the minimum

absolute pressure value (mbar)

of the suction manifold in the

maps: usually it is suitable to

set a value of about 200-

300mbar under MAP value at

idling;

By clicking on ADVANCED key

in the section concerning injectors

and other components, it is possi-

ble to display the injector charac-

teristics. It is possible you have to

read them to BRC technical

Assistance service in case of prob-

lems.

A similar section could be

4.2.1.3 Temperature sensors

Calibration (only for CNG)

It is the third step of the aided

procedure in case of a CNG equip-

ment; it is not displayed in case of

a LPG one (see picture 4.1) and it

is useful to calibrate the tempera-

ture sensor of the engine cooling

water so that it can be read and

used by the ECU.

Choose sensor enabled if the

original cooling water temperature

sensor of the petrol engine has

been connected (picture 4.5).

By choosing this second option

it is necessary to calibrate the sen-

sor. To do it the vehicle has to be

cold.

If not it is possible, choose the

option sensor Disabled in this sec-

tion and calibrate it later, out of the

aided procedure, through the suit-

able option from the Setting up

menu.

To calibrate the sensor follow

this procedure:

1. Select Sensor Enabled (see

picture 4.6).

2. Click on Calibration key.

Pic. 4.5 - Aided procedure – Temperature sensors calibration

Pic. 4.6 - Aided procedure – Temperature sensors calibration – first value acquisition

3. Click on the Acquire key to

memorise the temperature when

the vehicle is cold. This operation

will take a few seconds.

Note: This acquisition has to

be carried out when the tem-

perature of the engine water is

enough cold. For example at 40°C.

4. Introduce the Cold Vehicle T

value corresponding to the

acquired engine water temperature

in °C (i.e. 40 °C) as indicated in

picture 4.7 and confirm with OK.

5. Switch the engine on and

wait till the temperature is enough

high and acquire the temperature

with warm vehicle cl icking on

Acquire key (picture 4.8). For

example you can wait for the fan

operation which occurs around

100 °C.

6. Introduce the warm Vehicle T

value corresponding to the

acquired engine water temperature

in °C as indicated in picture 4.9

(i.e. 100 °C if you wait for the van

operation to acquire the tempera-

ture with warm vehicle).

After finishing this calibration,

go on with Next key; if it has been

modified you will be asked to con-

firm the introduced values. Usually

the answer is positive and in this

case all data will be memorised

(the previous ones will be deleted)

and you will approach the next

step.

With a negative answer old

data wi l l be kept and you wi l l

approach the next step. By clicking

on Cancel you will stay in the cur-

rent page and you will not continue

the procedure.

4.2.1.4 Rpm calibration

This if the third step in case of

LPG installation and the forth one

in case of a CNG one (see picture

4.1)

Entering the rpm calibration

sect ion, in the Set rpm signal

menu, the rpm signal type will be

displayed as it is read according to

the current ECU definition (see

picture 4.10).

If rpm value is not correctly

read, it is necessary to carry out

the automatic calibration proce-

dure by using Change Calibration

key.

The program will ask to keep

the engine at idle while running

with petrol (see picture 4.11).

You just have to confirm with

OK to automatically take the rpm

signal type.

At this point, if the rpm is one of

the system set ones, its name will

be displayed in the rpm signal type

taken by the automatic procedure

menu. In case the used rpm signal

is not in the list, the message ”No

determined setting” so appears

that you will have to manually set

the parameters through the indica-

t ions appearing by cl icking on

ADVANCED key. (For this opera-

tion please contact BRC techni-

cians).

If the automatic procedure took

a known rpm signal (it usually hap-

pens) you just need to click on

Confirm to continue (picture 4.13).

At this point it is better to verify

rpm are correctly read and this

control could be made, for exam-

ple, at idle and at 3000 rpm.

If everything is correct, click on

NEXT, and positively answer to the

confirmation question; then contin-

ue the Aided Procedure.

4.2.1.5 TPS Calibration

This is the fourth step for LPG

installations and the fifth one for

CNG (see picture 4.1).

Entering the screen for the TPS

calibration, the procedure auto-

matically begins (picture 4.15).

First of all it is necessary to verify

the operation conditions (the ones

written in blue at the top of the

screen). The vehicle has to be

stopped with the engine running

on petrol.

At the beginning the engine has

to be on with the accelerator com-

pletely released. After the program

will indicate to execute three com-

plete and uniform accelerations.

It the TPS calibration has not

been correctly executed it is possi-

ble to modify i t by cl icking on

Change Calibration key as indicat-

ed in picture 4.15.

At the end, click on Next, con-

firm the acquisitions and continue

the Aided Procedure.

4.2.1.6 Oxygen Sensor

Calibration

It is the fifth step for LPG instal-

lation and the sixth one for CNG

(see picture 4.1).

The Oxygen sensor calibration

is very important for this system as

this signal is used to speed up and

optimize the self-learning strategy.

It is important to know some

oxygen sensor characteristics such

as if it is a “CURRENT” or a “VOLT-

AGE” one (ordinary oxygen sen-

sor), if it is “straight” or “reverse”.

Let’s explain the meaning:

• Straight Oxygen sensor: the

high tension level corresponds

to a “rich” situation of the mix-

ture and, on the contrary, the

low tension level to a “lean” situ-

ation of the mixture.

• Reverse Oxygen sensor: the

opposite of Straight one.

Note: usually if the oxygen sen-

sor is a current type, it is a reverse

one, too.

Identification method: with a

sharp acceleration and standing

still, execute a cut- off (released

condition where there is no injec-

tion); if the oxygen sensor is low it

is a Straight one otherwise it is a

Reverse one.

The Current oxygen sensor is

recognisable for its extremely differ-

ent behaviour compared to the

Voltage oxygen sensor one.

During stationary conditions (at

idle) when the vehicle is in control,

a voltage oxygen sensor continu-

ously varies between minimum and

maximum tension value while a

current one will keep practically the

same value.

Only executing sharp tip-in or

during an open-loop phase, this

value notably changes. Please

remember current oxygen sensors

are mainly used by some car man-

ufacturers (i.e. Volkswagen) and

the mostly have more that 4 cables.

Once these parameters are set

and verified, continue the oxygen

sensor signal calibration. With the

engine at about 3000 rpm wait till

oxygen sensor start to check (see

picture 4.16) them click on Next

(not the one at the bottom of the

screen or you will directly go to the

next step) and start the automatic

calibration procedure. Keep the

engine at 3000 rpm and wait till the

program acquires the oxygen sen-

sor working range (see picture

4.17).

The calibration could be repeat-

ed, in case of mistakes, by clicking

Calibration, executing again all the

above listed operations.

At the end click on Next again

and confirm the acquired data.

4.2.1.7 FSF file Saving

This is the sixth step for LPG

installation and the seventh one

for CNG (see picture 4.1).

This section requires to select

the destination file where the set-

tings dotained up to now have to

be saved. Under the main f i le

USER_MAPS select the type of

installation (LPG or CNG) and fill

the below cel ls in, indicat ing

Trademark, Model, ECU, File (pic-

ture 4.18) in the most detailed

way.

For example, in case of a vehi-

cle with the following characteris-

tics:

Installation: CNG

Trademark: Ford

Model: Mondeo 1800i 16v

(BWY)

ECU: Visteon LBO-110 Levanta

File: AZ982BP

we will obtain what indicated in

picture 4.18:

Note: in choosing the file

name you can use whatever

you prefer. A good suggestion is to

use a name which makes you

identify the vehicle where the file

has been downloaded (for exam-

ple the plate number).

With the engine off and the

ignition key on, it is possible to

click on Save that means all cali-

brations will be saved on the PC

and downloaded in the ECU.

Clicking Exit, without saving, all

executed calibrations will be lost.

Choosing to continue, after the

ECU programming, you will have

to switch the dashboard off and

then on and after click on Next: at

this point you enter the self-map-

ping section.

4.2.1.8 Self-mapping

SEQUENT system bases its

operation on the maps contained

in the ECU which allow to translate

the petrol injectors signals into

orders for the gas injectors. These

are different according to the vehi-

cle. The aim of the self-mapping is

to obtain the translation maps

through simple acquisitions (on

road) of the vehicle operating con-

dit ions, immediately after the

installation.

There is also a self-learning

function able to correct possible

map error following the slow varia-

tions due to the system ageing, a

calibration loss or a slow deteriora-

tion of gas and petrol components.

To make the self-mapping and

the self-learning possible, it is nec-

essary to acquire and store two

maps, one for the petrol operation

and the other for the gas one. The

translat ion from petrol to gas

comes from the union and compar-

ison of these two information car-

ried out by the ECU.

The vehicle map procedure fol-

lows the phases listed hereunder:

1.Petrol Self-mapping

2.Creation of the gas operation

rough map

3.Gas Self-mapping

4.Map and full load check.

4.2.1.8.1 PETROL MAP

In this phase, during petrol

operat ion, the instal ler has to

acquire different operation points,

related to rpm and manifold pres-

sure (MAP). The PC program will

obtain the complete map during

petrol operation by means of suit-

able extrapolation algorithms.

The map is based on a table

with 16 lines and 16 columns. On

each line there are 16 points with

constant rpm while the MAP (suc-

tion manifold pressure) increases

23

Pic. 4.18 -Aided Procedure – FSF file saving

moving to the right. On the con-

trary, in each column the MAP

value does not change while rpm

increase moving down.

Please keep in mind the MAP

value increases (on the same rpm)

according the throttle valve open-

ing to (that is pressing the acceler-

ator more); therefore during the

self-mapping we move to the right

on the map by accelerating, shift-

ing up and looking for hil l trial

courses.

To move down the cartography

you have to achieve very high

rpm, for example, increasing the

vehicle speed, shifting down, etc.

In this case, the white column on

the left of the screen, with values

from 300 to 6250, contains rpm

values concerning to each line of

the table. At the same time, the

high white line with values from

125 to 965 contains the MAP value

in mbar concerning each column

of the map. At the beginning the

cells of this table are red and the

inside value is zero “O”.

The cell where you are corre-

sponding to the current rpm and

MAP collected by the system is

enlarged during the acquisition

(see picture); at the same time

rpm and MAP values concerning

the centre of the cell are displayed

in blue on the border of the table

In the upper cells, indicated as

RPM and MAP, the vehicle real

values are displayed as shown in

picture 4.20. The displayed cell

keep to have value “0” till the oper-

ation points acquisition does not

begin. This acquisition starts as

soon as we achieve the optimal

conditions (reducer temperature,

engine on for enough t ime,

changeover switch in petrol posi-

tion, constant operation conditions,

etc) and the Start key (at the bot-

tom left) has been pushed. The

value “0” starts to increase as

shown in picture 4.20. The techni-

cian is informing again the map

phase begins through the mes-

sage Acquisition in progress (at

the bottom of the screen).

Going on with the description of

the screen shown in picture 4.20,

besides the first two cells at the

top left (RPM and MAP) we have

the following information;

• Petrol duty-cycle inj.: shows

the value picked up by the sys-

tem in that moment for the

petrol injectors Duty Cycle;

• Lambda 1: shows the oxygen

sensor electric value;

In the upper part of the screen

(picture 4.20) we have three files:

1.Petrol Map

2.First gas map

24

Pic. 4.19 - Aided Procedure – petrol self-mapping beginning

Pic. 4.20 - Aided Procedure – petrol self-mapping

3.Second gas map

Only the first file is selectable

and active when you start a new

map, while the other two are auto-

matically activated by the program

itself. Fit the end of petrol self-

mapping begins the gas one. All

these files can be selected and

activated by the user when he

decides to continue a previous

stopped self-mapping, where the

petrol map processing was carried

out. While some operation points

are acquired in the same cell, its

colour changes from red to yellow.

This indicates that operation point

has been acquired with few points

but it can be used by the extrapo-

lation algorithms which calculate

the complete map (see picture

4.21). Going on in acquiring oper-

ation points in the same cell, the

colour becomes green indicating

the acquired points are enough for

a good map. When the number

contained in the cell achieves the

maximum (for example 50), the

next acquired point wil l be not

memorised and used to develop

the final map; also the number in

the cell does not increase any-

more.

A good map could be obtained

by acquiring more cells as possi-

ble, avoiding to leave a big area of

the map without acquisition (red),

for example full load or high rpm,

etc.) The ideal situation is to obtain

a map with many green points for

all MAP and rpm values (i.e. see

picture 4.22).

The points acquisition can be

stopped anytime (for example if

traffic conditions are averse) click-

ing Stop at the bottom left (picture

4.21) and started again clicking

the same key (the wri t ing wi l l

change into Start – picture 4.22).

When the table contains

enough wel l distr ibuted green

and/or yellow cells, it is possible to

continue the interpolation of the

missed points (red) with the cre-

ation of the final petrol map. To do

that, stop the points acquisition

clicking Stop and then Compute at

the right bottom of the screen (pic-

ture 4.22). This operation begins, if

possible, the acquired data pro-

cessing, creats the petrol map, an

initial gas one and transfers every-

thing in the ECU. At this point the

procedure moves to the screen for

the first gas map.

4.2.1.8.2 GAS SELF-MAPPING

At the end of the petrol map

phase, you can start the gas one.

The gas self-mapping is divided in

two steps:

1.First gas map

25

Pic. 4.21 - Aided Procedure – petrol self-mapping with some points

Pic. 4.22 - Aided Procedure – complete petrol map

2.Second gas map

To start the acquisition of the

first gas map, click on Start at the

bottom left.

At the bottom of the screen

there is a red writing as shown in

picture 4.23 asking to manually

change to gas and wait for stready

conditions (condition=3). The pro-

gram waits for the operator, carry-

ing the map out, changes to gas

operat ion with the Gas/Petrol

changeover switch. Only after this

change-over the vehicle begins to

be fed with gas following the initial

map which has been downloaded

at the end of the petrol map (see

picture 4.24).

This phase is extremely difficult

and delicate because the initial

gas map, downloaded from the

ECU, could be very far from the

correct one. The init ial map is

obtained from the gasoline map

through the multiplicative coeffi-

cient shown at the top right (pic-

ture 4.32). As we do not know the

correct value of this coefficient, dif-

ferent for each vehicle, it is possi-

ble the engine stops after the

change-over. If it happens, there is

no data loss and it is possible to

start again from the point the self-

mapping was left before the acci-

dental stop. As general suggestion

in order to avoid this inconve-

nience, remember that i f the

change-over is executed keeping

the engine rpm not too low (i.e.

2000 or 3000 rpm), lightly acceler-

ating, it is difficult this stop occurs

for a carburation defect. When the

change-over is carrying out during

vehicle movement and in gear, the

accidental stop is not possible as

the vehicle motion inertia will keep

the engine rotation and in this

lapse of time the technician can

change to petrol before the stop.

If this stratagem is not sufficient

to avoid engine stopping, it will be

necessary to start again from the

petrol self-mapping (picture 4.32)

introducing different values for the

multiplicative coefficient and click-

ing Compute till you find the value

which allows the engine to stay on.

The value of the multiplicative

coefficient has to be increased if

the vehicle stops after the engine

flooding or too rich carburation.

The reason of the stop can be

deduced from the oxygen sensor

behaviour immediately after the

change-over or before the stop.

During the self-mapping phase we

strongly suggest the use of instru-

ments able to display fast evolu-

tion of the oxygen sensor signal

(Jolly or Diagnostic Box). A typical

value of the multiplicative coeffi-

cient to start from is about 0,80.

26

Pic. 4.23 - Aided Procedure – first gas map beginning

Pic. 4.24: Aided Procedure – first gas map

Achieving the stationary condi-

tions, the program begins to calcu-

late the best fuel quantity to supply

according to the engine operation

conditions. During this phase try to

keep the operat ion condit ions

more constant as possible (stand-

still accelerator and constant rpm).

The red writing of the screen dis-

appears and in the % Map Error

cell we have a numerical value

indicating the entity of the correc-

tion executed by the program to

achieve ideal carburation condi-

tions (see picture 4.25).

While the program achieves a

more precise correction, the map

error decreases till it is less than

the set maximum error (this latter

could be set through OTHER).

When it occurs, the multiplicative

coefficient cell changes from red to

green and the initial value changes

too (see picture 4.30 whose value

decreases from 0,80 to 0,79).

Wait for a few seconds to be

sure the new multiplicative coeffi-

cient value (0,79 in picture 4.26) is

fixed then click on Stop and down-

load the new map obtained from

the petrol one and the new multi-

plicative coefficient.

You will be asked to change to

petrol (condition = 2 or 1) so set

the changeover switch in the petrol

position to make the map down-

load in the ECU possible.

The other cells in this screen

have the following meaning:

• Petrol Duty-cycle inj.: shows

the duty cycle taken from the

petrol injectors (cut and emulat-

ed).

• Reference Duty-cycle:

shows the petrol duty cycle

value expected by the map in

that point.

• % Map error: shows the

medium shifting between the

petrol duty cycle and the refer-

ence one; it is positive if the

petrol inj. duty cycle is bigger

than the reference one that

usually means the gas map is

lean or the petrol map has too

low values.

• Lambda1: it has the same

meaning of the petrol self-map-

ping.

27

Pic. 4.25 - Aided Procedure – first gas map after change-over

Pic. 4.26 - Aided Procedure – complete first gas map

Speeding up of the multiplica-

tive coefficient acquisition is possi-

ble increasing the maximum error

value using ADVANCED key (see

picture 4.27) and the sliding bar.

Consider that high value for the

maximum error lead to obtain

imprecise maps so that we sug-

gest not to exceed the value more

than 10%.

At the end of the first gas map,

the program asks to manual ly

change to gas and to wait stready

operation conditions (condition =

13, displayed clicking ADVANCED)

as indicated in picture 4.28.

After the change-over the pro-

gram automatically goes to the

second gas map screen (picture

4.29).

This screen, as the petrol one,

has 16 lines and 16 columns. The

functionality of the screen is simi-

lar to the petrol mapping proce-

dure one. The gas self-mapping

one is trained clicking Start. The

principle is similar to the petrol

mapping; the substantial differ-

ence is that, for each cell, the sys-

tem tries to correct the carburation

before starting to acquire the oper-

28

Pic. 4.27 - Aided Procedure – first gas map with ADVANCED key

Pic. 4.28 - Aided Procedure – complete first gas map

Pic. 4.29 - Aided Procedure – second gas map beginning

ation points. These latter, repre-

sented by the cel ls, are not

acquired till the Map Error is not

less then the set Maximum Error

value (see picture 4.30).

The carburation centering is

made for each cel l and stops

whenever you go on contiguous

cells; moreover it waits maximum

error and waiting time limits are

respected . For these reasons this

procedure is slower than the petrol

one and requires the conditions to

be constant for a longer time.

At the beginning the map is

zero and all cells are red (picture

4.29). While you execute some

acquisitions the colour changes

from red to yellow and then to

green and, at the same time, the

inside number increases. The

acquisition criteria is the same of

the petrol mapping. In the picture

4.31 we show the example of a

complete map.

To end the gas map acquisition

just click Stop, at the bottom left.

Before executing the data pro-

cessing you have to manual ly

change to petrol operation by turn-

ing the petrol/gas changeover

switch.

If the change-over does not

occur it will be not possible to con-

tinue the data processing; this

condition will be anyway displayed

with an error message. After a cor-

rect change-over, click Compute to

start the gas missed points inter-

polation and the download of the

final map to the ECU.

Note:

• There are some reasons

why the petrol or gas self-

mapping could create errors and

not correctly finish. This could hap-

pen is, for example, the acquired

points are not enough or if the

acquisitions are not plausible. The

not operating conditions will be

indicated with an error message. if

all conditions have been correctly

verified, the initial gas map is cre-

ated from the petrol one.

• The first gas map is created

from the petrol one and the multi-

plicative coefficient displayed click-

ing ADVANCED (picture 4.32).

Usually the coefficient value is

0,80. If you can not continue the

gas map, for example because the

initial map is too lean and the vehi-

cle stops when changing to gas, it

is possible to return to this phase,

modify the multiplicative coefficient

(for example increasing it to obtain

29

Pic. 4.30 - Aided Procedure – second gas map with an acquired point

Pic. 4.31 - Aided Procedure – complete second gas map

a richer map) and then click on

Compute again.

• When clicking ADVANCED

the Condition value is displayed;

this indicates the changeover

switch position and the injected

fuel: during normal petrol opera-

tion, with the changeover switch in

petrol position, with a sufficient

reducer temperature, the car run-

ning for enough time and in not tip-

in conditions, the cell has value 1.

In all other cases the value is dif-

ferent and the acquisition is not

executed. The gas temperature

and the change-over are repre-

sented by two sliding bars (picture

4.32): if the bars are completely

blue, acquisition conditions have

been achieved, on the contrary we

have to wait the temperature or

the ignition time reaching.

• I f you prefer to execute a

more precise petrol or gas self-

mapping, you can check its relia-

bility before executing the next

steps. To check it, leave the self-

mapping procedure by entering the

Setting Up screen and then the

Self-learning one. The value indi-

cating the map centering is con-

tained in % Error cell, at the top

left, as shown in picture 4.33.

Acceptable error values have to be

±5%. If more than ±10% the map

has to be considered not very cen-

tred. By staying a long on a not

centred point, the ECU self-learn-

ing will centre it better so that the

percentage error decreases. It is

possible to obtain more precise

and centred petrol maps running

on petrol after the petrol self-map-

ping and before executing the gas

one.

• Anytime it is possible to stop

an acquisition and start it again in

order to verify the centering or for

any other reason. For example,

after having executed part of the

petrol acquisition, that is before

downloading the map in the ECU,

it is possible to stop, switch the PC

off and start the work again later

recalling the name chosen at the

beginning of the map. The same

occurs if the petrol map has been

completed and downloaded in the

ECU. To start the work again, in

the main screen select Setting Up

and Self-mapping: you wil l be

asked to select the previously

saved vehicle file (picture 4.34).

By selecting the file, the map

screen will be opened by selecting

file (AB567CA.AAP).

To select the FSF file you have

to click twice on the file itself and

automatically a tick will be marked

near the Vehicle Parameters writ-

ing and the name of the selected

file will be displayed in the cell

below.

The selection of the software to

be downloaded (file .S19) is auto-

matically carried out when choos-

ing the Vehicle Parameters file (file

.FSF). To transfer it to the ECU it

is necessary the cel l near

Software writing is marked with a

tick. You can change the software

through ADVANCED, as indicated

in picture 4.38. Clicking it, a cell

containing the different available

software versions wi l l be dis-

played. We suggest to carry these

operations out only if advised by

BRC technicians or qualified per-

sonnel.

Click twice to select the .AAP

file and a tick will be automatically

marked near Mapping writing and

the name of the selected file will

be displayed in the below cell.

Pic. 4.38 - Programming from records – file S19 selection

The tick marks the files which

will be simultaneously downloaded

when continuing the ECU pro-

gramming clicking Program.

In Picture 4.39 all the three files

are simultaneously downloaded

(FSF, S19 e AAP).

At one time, it is possible to

make the following combinations:

• FSF

• AAP

• FSF + S19

• FSF + S19 + AAP

Sometimes it could be neces-

sary to update the loader on the

ECU. In this case the program

automatically informs the techni-

cian to do that when he chooses to

execute a guided personalised

programming of the ECU.

To update the loader, click on

LOADER UPDATING (see picture

4.39): the program will open a

page displaying a red writing with

all the indications, according to the

situat ion of the ECU. Cl icking

PROGRAM at the bottom of the

screen, the loader download

starts. At the end of this operation

a message will inform the opera-

tion has been correctly executed

and it is necessary to turn the igni-

tion key off and then on (picture

4.40).

NOTE:

While updating the ECU loader

you could face the following possi-

bilities:

1.The ECU contains a loader

version less than 106. In this case

the screen is the one of picture

4.40a and the writing in the centre

33

Pic. 4.39 - Programming from records – simultaneous selection of the three files

Pic. 4.40 - Correctly ended updating

Pic. 4.40a - ECU Loader updating if less than 106

informs the operation will be exe-

cuted in two steps: the first one

executes the loader programming

with 106 version (see picture

4.40b) and the second one will

download the most updated loader

available in the PC. At the end of

the first step you will be asked to

turn the ignition key off and then

on and click on OK (picture 4.40b)

At this point the second program-

ming starts and at the end a mes-

sage displaying it has been cor-

rectly executed appears (picture

4.40).

2.The ECU contains a loader

version higher or equal to 106, but

less than the last version con-

tained in the PC. in this case the

screen is the one of picture 4.40c

and the wri t ing in the centre

informs it is better to update the

ECU.

3.The ECU already contains

the last version. The screen is the

one displayed in picture 4.40d

where the writing in the centre

informs i t is not necessary to

update it.

4.The ECU has a loader ver-

sion more updated than the PC

one. This possibility occurs when

the PC has not been updated with

the last loader versions: in this

case we strongly suggest to

update the PC.

The screen is the one of picture

4.40e where the writing in the cen-

tre of the screen informs it is better

not to update the ECU as it will be

less updated than it is.

We suggest to carry this opera-

tion out only if advised by BRC

technicians or qualified personnel.

BE CAREFUL!:

• If the loader programming

stops as soon as it starts you have

to turn the ignition key off and then

on, and try again.

• Trying to update the loaders

start ing from versions less or

equal to 105, the programming

could be not executed in spite of

the repeated attempts. In this case

follow the listed indications:

1. From the main page select

PROGRAMMING > FROM

RECORDS

2. Select a start map from

BRC_MAPS.

3.In the VEHICLE PARAME-

TERS window, select the FSF file

in order to mark a tick on the cell.

4.Click on PROGRAM at the

bottom right to start the FSF pro-

gramming.

5.When the sliding bar indicat-

ing the programming process

appears, stop the communication

by turning the ignition key off and

then on.

6.Try again to update the

loader.

Selecting Setting up from the

main screen it is possible to enter

some sections dedicated to the

control and modification of the vehi-

cle parameters allowing to optimise

or correct the calibrations of a pre-

viously programmed vehicle (pic-

ture 5.0a). Most of the possible

operations are equivalent to the

aided personalised procedure ones

described in the previous chapter

so that here you will only find a ref-

erence to the concerned para-

graph. This chapter describes in

detail the different sections.

The changes introduced in the

setting up sections are marked with

a red “X” near the modified section

key (see picture 5.0b).

Leaving the setting up section,

you will be required to save the

modification on file, specifying the

type of installation, trademark,

model, ECU and file name (picture

5.0c).

5.1 PREVIOUSLYDESCRIBED FUNCTIONS

Selecting Setting up from the

main screen, the previously

described functions are the follow-

ing:

• Temperature sensors calibra-

tion.

• RPM Calibration.

36

5. SETTING UP

Pic. 5.0a - Setting up

• TPS Calibration.

• Oxygen sensor Calibration.

• Self-mapping.

Next paragraphs only describe

the new functions.

5.2 TYPE OFINSTALLA TION

This section allows to point out

the basic information of the installa-

tion, choosing between LPG or

CNG, and the vehicle type between

Vacuum or LPG Turbo. The choice

is marked with a tick in the circle

near the made selection.

In this screen you can also

select other installation characteris-

tics (picture 5.1) that are:

• Injector type: indicate the

installed type of gas injector choos-

ing among the available ones;

• N. of Genius: indicates how

many genius reducers have been

installed. Mostly it is one so that

this is the set value; it is necessary

to modify it only if you have two.

• N. of P1 Sensors: indicates

how many P1 pressure sensors

have been installed. The set value

is one. Modify it if you need to

install two (refer to installation plans

to know how many sensors are

needed).

• N. of Injectors: indicates the

total number of installed gas injec-

tors. Mainly they are 4 and this is

the set value. A message will indi-

cate the technician the number of

FLY SF ECU he has to install

according to the selected injectors

number.

NOTE:

By clicking ADVANCED key in

the installation section, it is possible

to set operation limits concerning

the rpm signal and the MAP mani-

fold pressure (picture 5.2).

Normally this operation has not to

be carried out unless indicated by

BRC technicians. In detail you

could set:

• Rpm Min: it is the minimum

rpm value in the maps: usually it is

suitable to set a value of about 300

rpm under the idl ing condit ion

value.

• Rpm Max: it is the maximum

rpm value in the maps: usually it is

suitable to set a value of about 500-

600giri/min under the vehicle rev up

value.

• MAP Min: it is the minimum

absolute pressure value (mbar) of

the suction manifold in the maps:

usually it is suitable to set a value

of about 200-300mbar under MAP

value at idling.

• MAP Max: it is the maximum

absolute pressure value (mbar) of

introduce the maximum value of the

achievable manifold pressure. In

case of vacuum engines set 1000

while for LPG turbo ones set 1700.

By clicking ADVANCED key in

the injectors and other components

section, you can display the injector

characteristics (picture 5.2b). In

case of problems it is possible you

wil l have to read them to BRC

Technical Assistance service.

Finish and verify the introduced

values, then click on EXIT to con-

tinue. The carried out modifications

have to be confirmed by clicking

YES when required.

5.3 LEVEL CALIBRA TION

This section allows to calibrate

the tank level sensor. A correct cali-

bration permits to display on the

petrol/gas changeover switch the

information concerning the filling

up.

At the beginning the values

memorised in the ECU are dis-

played but, if not correct, it is nec-

essary to calibrate the level sensor.

To carry out a correct calibration

the tank has to be empty in order to

get the level sensor signal clicking

empty tank acquisition; the regis-

tered value appears in the cell near

the key (picture 5.3).

After the gas filling up click on

full tank acquisit ion and the

obtained value appears in the cell

near the key.

Clicking on LPG (or CNG) set

values you can introduce some

standard values which normally

correspond to a correct calibration

of BRC resistive level sensor.

These values are:

For LPG

• Empty tank = 70mV

• Full tank = 1100mV

For CNG

• Empty tank = 70mV

• Full tank = 1050mV

You can set percentage discrim-

inating the passage among the dif-

ferent levels and the consequent

indication change on the

changeover switch. Usually these

values are set in order to have a

balanced division of the levels.

Anyway, if you wish to increase or

decrease the persistence of one of

the levels, to better set the indica-

tion, you need to manually modify

the values.

Clicking %->Electric the values

of the screen are displayed in mV

instead of as a percentage and vice

versa (picture 5.4).

Finish and verify the calibration,

38

Fig. 5.2b - Setting up – installation and injectors calibration by clicking ADVANCED key in the injectors section

Pic. 5.3 - Setting up – tank level calibration

then click on EXIT to continue. If

the adjustments have been modi-

fied, they have to be confirmed by

clicking YES when required.

5.4 P1-MAP

The P1-MAP sensor calibration

screen permits to select the

installed pressure sensor. It dis-

plays the different sensors avail-

able for the selected SEQUENT

installation.

In case of CNG or LPG turbo

vehicle (picture 5.5):

• SEQUENT P1-MAP

TURBO/METANO Fujikura pres-

sure sensor:

• SEQUENT P1-MAP

TURBO/METANO Motorola

pressure sensor:

In case of LPG installation (pic-

ture 5.6):

• SEQUENT P1-MAP LPG

Fujikura pressure sensor:

• SEQUENT P1-MAP LPG

Motorola pressure sensor:

For some vehicles, mainly the

ones studied by BRC, the vehicle

original MAP pressure sensor has

been used so that in this case it is

possible to execute a calibration of

this sensor clicking ADVANCED

key. The possible selections are, in

case of CNG or LPG turbo vehicle

(picture 5.7):

• SEQUENT P1

TURBO/METANO Fuijkura

(400kPa) pressure sensor

In case of LPG installation (pic-

ture 5.8):

• SEQUENT P1 LPG Fuijkura

(250kPa pressure sensor):

• SEQUENT P1 LPG Motorola

pressure sensor:

The MAP sensor calibration can

be executed in two ways, according

to the available instruments:

1.Calibration through P1

manometer.

2.Calibration through external

manometer.

The suggested operating condi-

tions for the acquisition are:

1.Engine off and ignition key on

(pressure 1000 mbar)

2.Engine at idle.

5.4.1 CALIBRA TION MAPTHROUGH P1

This option is based on the fact

the P1 pressure sensor has been

already set to execute the MAP

calibration, too. The program will

ask to disconnect the retroactive

pipe for the Genius (hear the itself)

and connect it to the P1 pressure

sensor inlet (see picture 5.9).

After this operation you just

need to keep the changeover

switch in petrol position, click on

OK and follow the program indica-

tions.

The calibration consists of the

Pic. 5.8 - Setting up – calibration P1-MAP calibration for LPG vehicles with original MAP

Fig. 5.9 - Setting up – MAP calibration through P1

following steps (picture 5.10):

1.Turn the vehicle ignition key

on and leave the engine off.

2.Click on Acquire: this opera-

tion will last few seconds.

3.Switch the engine on at idle

(see picture 5.11).

4.Click on Acquire: this opera-

tion will last few seconds.

At this point you just need to

confirm the calibration clicking OK

and after Exit, you will be asked to

confirm the set adjustments:

answer positively.

5.4.2 MAP CALIBRA TION

THROUGH EXTERNAL

PRESSURE GAUGE

It is possible to execute this

option only when you have an

external pressure gauge or a diag-

nosis equipment (often the diagnos-

tic handle computer AEB214 is

enough); when possible, this

method is surely the one allowing a

more precise, easier and faster cali-

bration.

The calibration consists in the

acquisition of two different vehicle

operation conditions and following

extrapolation of the characteristic

through an easy linearization.

Note: the diagnostic equipment

often gives the suction manifold

pressure in kPa (Kilo Pascal)

instead of mbar (mill ibar) as

required by the program.

The conversion formula to obtain

the value in kPa, Knowing the mbar

one, is the following:

mbar value = kPa value * 10

For example 42 kPa correspond

to 420 mbar.

The calibration procedure con-

sists of the following steps (see pic-

41

Pic. 5.10 - Setting up – MAP calibration through P1, first value acquisition

Pic. 5.11 - Setting up – MAP calibration through P1, second value acquisition

Pic. 5.12 - Setting up – MAP calibration through external pressure gauge

ture 5.12):

1.Turn the vehicle ignition key on

and leave the engine off;

2.Click on Acquire: this operation

will last few seconds.

3.In Physical 1, introduce the

mbar value read by the pressure

gauge (or by the diagnostic equip-

ment) and click on OK (see picture

5.13).

4.Switch the engine on at idle

(see picture 5.14).

5.Click on Acquire: this operation

will last few seconds.

6.In Physical 2 , introduce the

mbar value read by the pressure

gauge (or by the diagnostic equip-

ment) and click on OK (see picture

5.15).

At this point you just need to

confirm the calibration clicking OK

and after Exit. You will be asked to

confirm the set adjustments.

5.5 CHANGE-OVER

This screen allows to modify the

parameters for the petrol-gas

change-over. Two sections have

been displayed in red (see picture

5.16):

1.Cold engine

2.Warm engine

The first is necessary to the

gas/petrol change-over calibration

when the vehicle is cold (for exam-

ple after a long stop without starting

the engine); the second for the

change-over calibration when the

engine is warm (for example when

you start the engine after a short

stop) The reference temperature is

the genius one or, in case the vehi-

cle original sensor is connected

and calibrated, the engine cooling

water one.

In the Cold Engine section you

can introduce the following data:

• Change-over temperature

higher than: it corresponds to

the temperature we have to

achieve after the set time to

execute the change-over.

• Change-over Delay: it corre-

sponds to the waiting t ime

before verifying the change-over

temperature.

• Similar paragraphs are includ-

ed in the Warm Engine section.

Usually, in the Cold Engine sec-

tion, it is better to set a low change-

over temperature and a medium

long delay while in the Warm

Engine one it is better to set an

higher change-over temperature

and a lower delay.

Besides some parameters modi-

fication, the ADVANCED key per-

mits to execute the petrol/gas

change-over which normally occurs

if there is no gas in the tank or if the

gas temperature is too low.

This screen parameters have to

be modified only with BRC techni-

cians support.

The configurable parameters

(fig. 5.16a) are:

• MAP maximum value for the

change-over: it corresponds to

the manifold pressure value

under which it is possible to

change from gas to petrol.

• RPM maximum value for the

change-over: it corresponds to

the rpm value under which it is

possible to change from gas to

petrol.

• Petrol change-over tempera-

ture: it corresponds to the tem-

perature threshold under which

the petrol change-over occurs. it

43

Pic. 5.16 - Setting up – change-over parameters calibration

Fig. 5.16a - Setting up - change-over petrol parameters calibration

is possible to deactivate this

change-over introducing –41 °C

in this table.

• Minimum DeltaP: It corre-

sponds to the DeltaP value (dif-

ference between gas P1 pres-

sure and MAP) under which the

petrol change-over occurs.

• Maximum Duty cycle for the

change-over: It corresponds to

the gas injectors duty cycle

threshold over which the

change-over occurs.

• Waiting time for gas change-

over: indicates the time between

the conditions recognition allow-

ing to return to gas operation

and the real change-over.

• Waiting time for petrol change-

over: indicates the time between

the recognition of a possible

petrol change-over cause and

the real change-over.

• Waiting time for end gas warn-

ing signal: indicates the time

between the conditions recogni-

t ion of the gas end and the

warning signal.

• Fuel consumption threshold:

according to the type of installa-

tion and the injectors number,

this threshold is useful to know

when 0,5 petrol litres have been

consumed after the petrol

change-over.

5.6 TIP IN AND TIP OUT

When necessary, tip in and tip

out screens allow to calibrate the

setting up parameters to improve

the driving.

Let’s analyse the tip in screen.

In the upper part the rpm thresh-

olds subdividing the tip in are dis-

played in red. The below cells can

be set by the user and indicate the

tip in entry threshold based on the

TPS and rpm signals. A red arrow

indicates what is the condition of

the vehicle and consequently what

are the cells to be modified to

change the transient. The value to

introduce is always a positive one

and it can be understood from the

read one in the TPSFHPos% cell.

This latter indicates every second

the filtered TPS value; you just

have to read the inside value, dur-

ing a tip in you need to modify and

introduce it in the entry threshold

cells, where there is the tip in start-

ing condition.

For example, if you wish to mod-

ify a tip in at 1000 rpm, it is neces-

sary to modify the fifth and sixth

cell, identified by 900 and 1150 rpm

even if the tip in exceed this rpm

threshold, introducing as entry

threshold a value which is the same

to the one contained in the

TPSFHPos cell.

With an entry threshold value of

1000 in a cell concerning a certain

condition, the transients will be

deactivated for that condition.

The Transient Flow cells allow

to introduce a flow value to be

added to the tip in flow. A positive

one will rich the tip in while a nega-

tive one will make it lean. To give

an idea of the value to be intro-

duced, refer to the flow values dis-

played in the self-learning screen,

near the tip in.

The other parameters in the

screen are:

• Tip in exit threshold: indicates

the TPS threshold for the tip in

exit and usually it is negative:

the exit usually occurs with a

deceleration.

• Dissolving time: it is the con-

nection time to go from the tip in

flow to the one usually required

by the vehicle. This time begins

at the end of the upkeep one

and it is expressed in 1/1000 of

second, too.

• Petrol tip in %: indicates how

much the immediate petrol cor-

rection enter the gas tip in, that

is how much influence the petrol

ECU tip in has on the gas

44

Pic. 5.17 - Setting up – Tip in calibration

behaviour. 1000 corresponds to

use all the petrol contribution,

decreasing the value the contri-

bution proportionally decreases.

• Tip in condition: indicates the

vehicle condition.

Let’s analyse tip out in screen

(picture 5.18):

In the upper part the rpm thresh-

olds subdividing the tip out are dis-

played in red. The below cells can

be set by the user and indicate the

tip out entry threshold based on the

TPS and rpm signals. A red arrow

indicates what is the condition of

the vehicle and consequently what

are the cells to be modified to

change the tip out. The value to

introduce is always a positive one

and it can be understood from the

read one in the TPSFHNeg% cell.

This latter indicates every second

the filtered TPS value; you just

have to read the inside value, dur-

ing a tip out you need to modify and

introduce it in the entry threshold

cells, where there is the tip out

starting condition.

For example, if you wish to mod-

ify a tip out at 1000 rpm, it is neces-

sary to modify the fifth and sixth

cell, identified by 900 and 1150 rpm

even if the tip out exceed this rpm

threshold, introducing as entry

threshold a value which is the same

to the one contained in the

TPSFHNeg% cell.

With an entry threshold value of

1000 in a cell concerning a certain

condition, the tip out will be deacti-

vated for that condition.

The tip out Flow cells allow to

introduce a flow value to be added

to the tip out flow. A positive one

will rich the tip out while a negative

one will make it lean. To give an

idea of the value to be introduced,

refer to the flow values displayed in

the self-learning screen, near the

tip out.

The other parameters in the

screen are:

• Tip out exit threshold: indicates

the TPS threshold for the tip out

exit and usually it is negative:

the exit usually occurs with a

deceleration.

• Upkeep time: indicates the tip

out time. It is indicated in 1/1000

of second that is 1 second 0

1000.

• Dissolving time: it is the con-

nection time to go from the tip

out f low to the one usually

required by the vehicle. This

time begins at the end of the

upkeep one and it is expressed

in 1/1000 of second, too.

• Petrol tip out %: indicates how

much the immediate petrol cor-

rection enter the gas tip out, that

is how much influence the petrol

ECU tip out has on the gas

behaviour. 1000 corresponds to

use all the petrol contribution,

decreasing the value the contri-

bution proportionally decreases.

• Tip out condition: indicates the

vehicle condition.

5.7 SELF-LEARNING

During standard operation con-

ditions, after the mapping, the ECU

corrects the light calibration inaccu-

racies and follows the slow varia-

tions due to the system ageing, set-

ting up lost or the slow gas and

petrol components deterioration.

This is the self-learning function.

It is very important to well under-

stand the difference between self-

mapping and self-learning. The

self-mapping is executed only one

time during the vehicle installation

while the self-learning will work for

the whole gas installation life, keep-

ing the operation and calibration

conditions the best as possible.

The self-learning screen is use-

ful to verify and correct the center-

45

Pic. 5.18 - Setting up – Tip out calibration

ing of a map. There are three files:

• Petrol Map

• GAS Map

• Condition Map

To go from a file to another you

just have to click on the icon of the

file you need to display.

Each file consists of a table with

16 lines and 16 columns. Each cell

contains a contains the memorise

operating point according to rpm

and manifold pressure (MAP).

Particularly, the petrol map memo-

rised the petrol injectors duty cycle;

the gas map contains the memo-

rised gas flow according to the

petrol map and the extrapolation

algorithms while the condition map

contains the system operation con-

ditions according to the lambda

control carried out with petrol. It is

possible to set three different oper-

ation conditions:

• Closed loop = 4, for the areas

regularly checked by the oxygen

sensor.

• Open loop = 5, for the areas

which are not under the oxygen

sensor control.

• Indefinite = 7, for the “border”

areas between open loop (full

load) and closed loop (con-

trolled oxygen sensor) that are

those areas when you can have

open loop or closed loop condi-

tions according to the engine

load.

According to the selected condi-

tion the colour of the cells in the

petrol and gas map will be different:

• Green: for closed loop cells.

• Red: for open loop cells

• Yellow: for indefinite cells

The white ones (picture 5.19)

indicates the operation area

where the system is working. To

manually modify a cell value,

click on it, push the space-bar,

introduce the new value and

click on enter key.

The other parameters represent:

• RPM and MAP: they respec-

tively indicate the engine rota-

tion condition and the suction

manifold pressure (MAP)

• Petrol inj. DC: indicates the

petrol injection duty cycle

instantaneously taken from the

petrol injectors.

• Reference DC: indicates the

petrol injection duty cycle

expected by the map for the

specific operation point.

• GAS inj. DC: indicates the gas

injectors duty cycle.

• % error: indicates the average

difference between the petrol

injectors duty cycle and the ref-

erence one. It is positive if the

petrol injectors duty cycle is

higher that the reference one.

This has to be interpreted as the

signal of a lean gas map or of a

petrol map with too low values.

A graphic showing the oxygen

sensor behaviour is represented

hereunder and it is very useful to

identify the open loop and closed

loop areas.

The “Cancel last Digit” key

allows to settle the previous values

again.

At the bottom of the screen

there are two sliding bars. On the

left we have petrol self-learning

speed; on the right the gas self-

learning speed . These allow to

modify, decelerating and accelerat-

ing, the system self-learning algo-

rithms. For each parameter we

have 6 different speeds:

• Very fast

• Fast

• Medium

• Slow

• Very Slow

• Stopped

The control of a map centering

reliability consists of positioning in

different operation points with RPM

and MAP constant and check the

46

Pic. 5.19 - Setting up – self-learning

%Error value. A map can be con-

sidered centred is the error is less

than 5%. A not centred map or

areas could be brought to a good

level with a manual intervention or

reviewing the cells keeping the con-

ditions more constant as possible in

order to take the %error to a value

lower than 5%.

If some changes occur, when

leaving this screen you will be

asked to confirm them and they will

be saved later in the User_Maps

file and sent to the ECU.

6.1 DATA DISPLAY

Clicking on DIAGNOSTIC key

at the bottom of the main screen

and selecting Data display in the

left buttons, we enter the page

shown in picture 6.1 where it is

possible to display the different

ECU operat ion parameters as

numbers or with a graphic.

As indicated in picture 6.1 the

numerical values are listed on the

left while the graphs are more or

less in the centre. These latter can

be minimum one or maximum four

or even zero (pictures 6.1, 6.2,

6.3, 6.4 and 6.5)

To introduce a new graphic or

take one away you just have to

cl ick twice the corresponding

numerical value. When there are

four graphs, to add another it is

necessary to take away at least

one.

At the top of the graphs and the

numbers there are 6 square but-

tons, each with a particular func-

t ion described later. With the

mouse pointer on them, a writing

explaining the function will appear

for a few seconds. These functions

allow to execute file acquisition of

data and displayed parameters, to

change the numerical data list dis-

played on the screen choosing the

most interesting ones from the list,

to modify the list of the values

which will be saved in file choosing

the most interesting ones.

6.1.1 STORAGE PARAMETERS

The f irst left key with a f i le

allows to change the storage para-

meters that is the position where

the acquisition file creating in this

page will be saved. Clicking on the

key, the page in picture 6.6 will be

opened.

the same effect is obtained by

selecting “File” and then “Record

Parameters” from the menu bar (at

the top left). In the centre of the

screen, at the top, there is a big

file with all the previous acquisi-

tions characteristics.

Immediately under there is a

table titled “Data Sheet” where

there are different files to fill up:

you have to compulsori ly set

trademark, Model and Plate. the

others (Year, engine number, ECU

type, Power, Type of installation,

Note) are optional and wil l be

stored as a reminder in the

acquired file.

Let’s imagine to fill in trademark

with Fiat, Model with “Stilo 1.6i

16V (182B6000) Euro4”, and Plate

with “AJ280CN” (plate number); in

this case the acquisition file will

( 1 8 2 B 6 0 0 0 )

Euro4\AJ280CN.ACQ” (the posi-

tion could vary according to the

computer characteristics and to

the file where SEQUENT program

is installed).

Clicking on “Store” key, the file

where you will execute the data

acquisition will be created. Clicking

on “Exit”, data will be not stored

and the system returns to the pre-

vious page.

Please note that the new

record is stored in the top cell in

order to select it next time without

having to digi t the complete

address. Selecting it all the data

will appear in the cells, including

the notes you decided to add.

6.1.2 BEGINNING/RESTARTING

RECORD

When you push the second key

on the left with a red triangle with

the point to the r ight (as the

recorder PLAY button), the data

acquisition starts (see previous

paragraph to know where data will

be stored).

When the data acquisition is

active, the key changes into two

paral lel vert ical l ines (as the

recorder PAUSE button). If you

click on the key during this condi-

tion, the acquisition will be stopped

and the key becomes a triangle

again. Clicking it again, the acqui-

sition restarts adding new data to

the previous ones, without can-

celling them.

The same operations can be

executed by selecting on the bar

menu (at the top left) “Record” and

then “Beginning/Restarting record”

or by simply click on SHIFT+F2,

SHIFT+F5, SHIFT+F9 on the key-

board.

It is possible to stop the record

anytime by clicking on the STOP

key (a red square as the recorder

STOP button). Cl icking again

START or PLAY, the acquisition

starts again adding new data to

the previous ones, without can-

celling them.

6.1.3 GRAPHS BLOCKING

The forth left key can block dis-

played graphs and numerical val-

ues. First it contains a graph with a

red cross on. Clicking on it the

graphs will be blocked and the

numerical values do not change;

the key will contain a graph with-

out red cross.

By clicking on the key again,

the graphs will be deleted and you

have to start again from the begin-

ning while the numbers start again

to change.

6.1.4 SETTING

The fifth key from the left, at the

top of the data display page, is

used to choose what are the

numerical data to display and what

are the ones to be stored during

the acquisition.

As shown in picture 6.7, near

each value there are two cells

where the t ick mark has to be

added: the first refers to the dis-

played value. Selecting or dese-

lecting the cell, you add or remove

the data from the column. The

minimum data number is 1 and the

maximum is 10. If you already

have 10 values, you will have to

remove one to add another.

Under “Recorded” there are

some cells to select the data to

acquire and store on .ACQ file.

you can store the number you pre-

fer, even all, if you wish. Take care

that more data you have more the

acquisition file becomes long. In

the same way, the file enlarges

considering the acquisition length.

6.1.5 PAGE EXIT

Use the sixth key from the left,

at the top of the data display page,

to leave the page.

The same could be obtained

with EXIT key at the bottom centre

of the page or by clicking the enter

key when framed in a broken line.

6.2 ACTUATORS TEST

When the ECU has been pro-

grammed with a basic map it is

important to verify the correspon-

dence of the injectors, the signal

coming from the petrol injector 1

has to be the same of the gas

injector 1, and this for all the injec-

tors.

Possible errors for this connec-

tion do not create big problems for

the vehicle operation during sta-

bilised running, but are strongly

perceptible during t ip in and

change-over.

The inversion of two injectors is

very dangerous during change-

over as, for a certain period, one

cylinder will be fed with both petrol

and gas while the other one will

not receive any fuel.

In picture 6.8 we have a cor-

rect injectors connection while in

picture AM45 gas injector 1 and 2

have been reversed.

In the SEQUENT system the

change-over in carried out in order

to change-over one injector each

time to make the petrol to gas pas-

sage milder and vice versa. This

means that in a 4 cylinder vehicle

the petrol feeds three cylinders

and the other with gas, then two

cylinders with petrol and two with

gas, then one with petrol and three

with gas till reaching a full gas

operation for all cylinders. Some

engine cycles which could be set

from installers program (normally

3) have to be executed between

an injector change-over and

another one.

In the picture 6.8 at the

change-over happens the follow-

ing:

• The petrol 1 injector is cut and

the gas 1 injector is piloted.

• After 3 injections the petrol 2

injector is cut, too and the gas 2

injector is piloted

• After other 3 injections the

petrol 3 injector is cut, too and the

gas 3 injector is piloted.

• Again After other 3 injections

the petrol 4 injector is cut, too and

the gas 4 injector is piloted.

In this case during the change-

over all the cylinders are continu-

ously fed with a one and only fuel.

Pic. 6.8 - Correct installation example

Pic. 6.9 - Wrong installation example

52

In case of wrong installation

(picture 6.8) it happens what indi-

cated hereunder:

• The petrol 1 injector is cut and

the gas 2 injector is piloted.

• After 3 injections the petrol 2

injector is cut, too and the gas

1 injector is piloted.

• After other 3 injections the

petrol 3 injector is cut, too and

the gas 3 injector is piloted.

• Again After other 3 injections

the petrol 4 injector is cut, too

and the gas 4 injector is piloted.

This means that during the first

phase the cylinder 1 is not fed

while the cylinder 2 receives both

petrol and gas.

To easily find possible error in

the injectors electric connection

there is a program screen called

“Actuators test” (picture 6.10) and

you can f ind i t in Diagnost ic

Actuators Test.

When entering this screen the

program reads on the ECU how

many injectors are connected to

the ECU itself (4 in the example)

and what is the delay for the injec-

tions number between the change-

over in a cylinder and the one in

the next one (3 in the example).

By taking the tick marks away

from the injectors it is possible to

make the cylinders immediately

fed with petrol even i f the

changeover switch is turned to gas

position and the led is green: then

you can decide (in case of 4 cylin-

ders) to make the engine work

with 3 cylinders with gas and 1

with petrol, or 2 with gas and 2

with petrol, or 1 with gas and 3

with petrol or, finally, all the 4 with

petrol. Note that in this latter case

even if the vehicle correctly runs

on petrol, the changeover switch

led is green, the solenoidvalves

open (or they will open at change-

over) and this behaviour can cre-

ate confusion. Moving the sliding

bar to the right it is possible to

increase the change-over delay

between two consecutive injectors.

Procedure for the identification

of injectors connection errors:

Let’s suppose to have the same

situation described in the picture

6.9 and you want to verify if the

injectors have been correctly con-

nected.

Increasing the change-over

delay the time during which the

vehicle has a not fed cylinder (the

first) and another one fed with both

fuels (the second) increases too

and you will easy feel the engine

“is working bad” or switch off.

At this point you know there

was a change in the connection of

the injectors but you do not know

what are the inverted ones.The

procedure is the following.

Procedure for the correction of

injectors connection errors:

1. Take the tick marks away

from each injectors cell. the

engine will work with petrol.

2. Add a tick in the injector 1

cell.

3. If the gas injector supply gas

in the correct cylinder (that is

the petrol 1 injector) the engine

will correctly work. In this case

repeat the point 1 with the next

injector. On the contrary, i f

there are some problems, go to

the point 4.

4. The selected gas injector has

to be moved: move the connec-

tor on another gas injector till

obtaining the engine correct

operation.

5. Repeat the point 1 with the

next injector till finding the cor-

rect connection for all the gas

injectors.

6.3 ECU VERSION

With DIAGNOSTIC key at the

bottom of the main screen and

selecting ECU VERSION among

the left keys, you enter the page of

picture 6.11 with the parameters

identifying the software type, the

data and other parameters regard-

ing the ECU programming.

6.3.1 PARAMETERS DESCRIP-TION

6.3.1.1 ECU Code

It is the code of the component

which represents this particular

type of ECU. For example the one

in the picture is “DE813001-00-00”

and identify the first version of the

FLY SF ECU for 4 injectors.

This code is divided in a main

one (DE813001) for the compo-

nent (FLY SF ECU for 4 injectors),

and two sub-codes divided with a

stroke identifying the main and

secondary hardware revision.

6.3.1.2 Loader version

Identify the loader version in

the ECU memory. It is displayed

as a letters and numbers

sequence as the following: “KER-

FS 0113”. The last four numbers

represents the version (in this

case 113). Higher is this number

and more recent and improved will

be the loader.

6.3.1.3 Software version

It is the real software contained

in the ECU. It is composed by 5

letters + 3 numbers + 3 numbers.

The first 5 letters indicates the

software, the other 3 numbers the

real software version (higher is this

number and more recent and

improved wil l be the program)

while the last 3 indicates the hard-

ware version.

6.3.1.4 Map version

It is the ECU map version (file

.AAP) (not the calibrations version

that is .FSF). For BRC maps it is

at least 1: this number is increased

each time BRC develop a new ver-

sion.

For the maps developed by the

technician this number is always 0.

6.3.1.5 Vehicle code

This number is paired to each

vehicle developed and confirmed

by BRC. Its value is 65535 if the

map has been developed by the

technician with the guided person-

alised procedure. If the technician

creates a new map by modifying a

BRC one, without using the guided

personalised procedure, the BRC

original vehicle code won’t be

change.

6.3.1.6 Calibrations V ersion

It is the ECU calibrations ver-

sion (file .FSF) (not the mapping

version that is .AAP). For BRC

maps it is at least 1: this number is

increased each time BRC develop

a new version.

For the maps developed by the

technician this number is always 0.

6.3.1.7 First programming date

It is the date in which the ECU

has been programmed for the first

time by the technician. After the

first one, this date won’t change

for the ECU all life long.

6.3.1.8 Programming code

It identifies the type of program

used in the PC to execute the last

ECU programming.

Usual ly i t could be

“PROG_INS”, to indicate

SEQUENT technician program has

been used.

Pic. 6.11 - Diagnostic – ECU Version

54

The different available func-

tions in UTILITY allow to carry out

different operations to update the

program or modify some aspects.

All these functions have not to

be connected to an ECU except

for the “SAVE CONFIGURATION”

option allowing to update maps

and calibrations on the PC extract-

ing them from an ECU and adding

them to the technician PC record.

After select ing “UTILITY” the

screen becomes as in picture 7.1

and on the left there are various

instruments we will describe in the

next paragraphs.

7.1 LANGUAGE CHOICE

I t permits to select the lan-

guage for the program (messages,

writings, captions and all the dis-

played information). The program

is studied to change the language

introducing a file (a .LNG file) in

the installation file (usually “C:\pro-

grammi\SEQUENT). the procedure

for the selection is the following:

1. Start SEQUENT program.

2. Select “UTILITY” from the

main page.

3. Click “LANGUAGE CHOICE”

key, on the left of the screen.

4. Select the language file in

“AVAILABLE LANGUAGES”

(see picture 7.2).

5. Click “CHOOSE” key at the

bottom of the screen,

6. Click “EXIT” key to return to

main page.

Cl icking on “EXIT” key or

escape one on the keyboard (at

the top left “Esc”) you leave this

page without executing changes.

7.2 COMMUNICATION

It allows to modify the parame-

ters of the communication between

PC and ECU. It is necessary to

modify these options especially

when the PC has not a serial plug.

In this case use an USB/serial

adapter to add a virtual door to the

PC. In the “Serial” file (picture 7.3)

the “COM 1” value has to be sub-

stituted according to the value the

operat ive system set for the

adapter (see Windows® control

panel, “System” option).

The “Baud rate” file (picture

7.3) allows to modify the transmis-

7. UTILITY

Pic. 7.2 - Utility – Language choice

55

sion speed. If there are not partic-

ular problems, we suggest to leave

the maximum speed of 19200

Baud, with whom you have the

minimum times of the ECU pro-

gramming. The other programming

speeds are 10400 Baud and 9600

Baud (standard ones).

Another interesting parameter

is the “Waiting time between 2 fol-

lowing messages”. Decreasing this

time you obtain higher speed for

the ECU programming but higher

possibilities the communication

fail, too. The suggested standard

value is 150 ms, except in case of

problems.

The “Fast init. hooking” key is

used to select the initialisation type

has to be used to start the commu-

nication between PC and ECU.

Usually it has to be selected.

The options appearing clicking

on “ADVANCED” has to be

changed only in case of problems

and only with the help of BRC

technicians or qualified personnel.

In case these parameters have

been modified causing the impos-

sibility to dialogue with the ECU,

restore standard values. You can

know the value of each cell placing

the mouse pointer on them: a

small cell with the standard value

will be displayed and will disap-

pear when moving the pointer.

To save the changes and return

to the main page, click “SAVE” key

at the bottom of the screen. To

leave without saving the modifica-

tions and return to the main page,

click “EXIT” key or the escape one

on the keyboard (at the top left

“Esc”).

7.6 DISKS CREATION

This key allows to create disks

with the maps taken from the PC

user record in order to transfer

them in another PC. With this pro-

cedure it is not possible to transfer

the maps of the BRC record, the

software or the loader to another

PC. to update the software and

loader it is necessary to download

the updating one from BRC inter-

net site or from CDROM or disks.

Each disk created by the user

can contain various maps till the

exhaustion of the available space.

The procedure to be carried out

to transfer a map on the diskette is

the following (see picture 7.7):

1. Start SEQUENT program in

the PC containing the map you

wish to transfer.

2. Introduce an empty disk in

the PC.

3. Select “UTILITY” key in the

main page.

4. Click on “DISKS CREATION”

key.

5. In the user record select

“LPG” if it is a LPG vehicle map

or CNG if it is a CNG one.

6. Select the trademark, model

and type of ECU relating to the

map you wish to transfer.

7. If you want to deepen a self-

mapping, adding other points, it

is possible by selecting “copy

self-mapping file”. Keep in mind

that even if you are not interest-

ed in continuing a self-map-

ping, the additional files saving

is not dangerous (it only fills

more space in the disk and in

the PC hard Disk).

8. Click on “SAVE” key at the

bottom of the screen.

9. When the copy operation is

completed, you can repeat it

starting from step 4 till there are

maps to be transferred or till

you have available space. (in

this case you have to repeat

the not successfully concluded

operation after having replaced

the disk with a new one).

ation, click on “EXIT” key to

return to the main page.

To transfer a map from the disk

to the new PC, follow the data
